As Christian Horner, boss of champions Red Bull, insisted Sunday’s German Grand Prix should still go ahead, the ex-F1 ace roared: “For me, Bernie, the FIA and Pirelli are bringing the sport into disrepute.

“They need to have a serious look at themselves and change these tyres and not expect all the teams to agree. You will never get all of the teams to agree, so take it out of their hands and put safe tyres on these cars.

“Bernie is in charge of Formula One, as are the FIA.

“They chose Pirelli and Pirelli are not living up to expectations so they have a responsibility to this sport to make sure that we have a sport that is safe enough for drivers and spectators to participate in.”

“These kerbs have been in since 2009 and we have had thousands and thousands of cars go over these kerbs and they have been absolutely fine,” he added.

F1 aces have threatened to boycott the next round in Germany on Sunday unless something is done.

“I don’t think they should cancel Germany,” said Horner, who wants the sport to revert to last year’s tyres which were problem-free.

“They need to understand what happened and react to that. I would urge the change purely on the grounds of safety. That comes before any performance criteria.”

Team bosses are to hold talks with Ecclestone and Todt to solve the crisis.

Pirelli, called to a Wednesday meeting with the FIA in Paris have long tried to change the tyres, but they have been blocked by Ferrari, Lotus and Force India, who fear they could lose their competitive advantage.

F1 legend Sir Jackie Stewart said the testing ban should lifted immediately and teams should be testing at Silverstone now rather than preparing for the next race.

“If we went into another Grand Prix or two and something really nasty were to happen we would never forgive ourselves,” he said.

“We have had too many accidents. Four from 22 is a big percentage. We cannot afford entertainment versus safety, danger and potential life-threatening situations.

“We have to put our house in order. Go for hard tyres and have two types of those if necessary.”

Silverstone’s planned young-driver test on July 17-19 will now be turned into a full-blooded run-out with F1 aces in the cockpits.
